Improvement in organ-stops



ALBERT K. HEBARD, OF BOSTON, MASSACHUSETTS.

Letters Patent No. 105.571, dated July 19,1870.

The Schedule referred to in these Lettera Patent:l and making part ofthe same,

To all persons to whom these presents shall come:

Be it known that I, ALBERT K. HEBARD; of Boston, in the county of Sniolkand State of Massachusetts, have invented certain new and usefulImprovements in Organ-Stops; and that the following is a full and exactdescription of the same, reference being had to the accompanyingdrawing.

The present invention relates to an arrangement of parts interposedbetween the register of the organ and the hinged cover to the reeds,Ste., for opening and closing the same.

The invention consists in a connection between the registerA and thecover to the reeds, Ste., disposed and arranged in such a manner that,in the opening of the stop, the pressure of the spring upon thereed-cover to hold it closed will be relieved by the action of saidconnection before the said cover is raised or opened.

The invention also consists in operating or opening and closing thereed-cover by and through the spring arranged to hold the reed-coverclosed, said spring being connected in a suitable manner with theregister therefor.

In the accompanying drawing my improvements in organ-stops areillustrated Figure 1 being a view of a serieso reed-chambers, with thecover thereto closed; Figure 2, an end view; and

Figure 3, a transverse section in plane of line x fc,

A, in the'diawing, represents a seriesof' reed-chambers as arranged in acommon frame, B, and properly constructed with angular grooves a, forthe reception of the reeds.

C, a cover to the reed-chambers A, hinged to the frame B, along one edgeorside,D, thereof, in suitable manner to be closed upon and opened fromthe reedchambers, as shown, respectively, in figs. 2 and 3.

E, a spring wire or rod passing along the length of reed-frame,connecting the two hinges F of the cover together, forming thecenterthereof.

This wire or rod, at one end, G, is fastened ordriyen into ,thereed-cover, and at the .other end, H, is -bent at right angles, 'orthereabout, and interlocked with a notch, I, ot' a block, J, arranged toslide upon one end of the reed-frame, being guided by its slot K moving'on the headed staple L,iixcd in the block.

To this block or slide J a register is to be connected in any suitablemanner, so that through the register the block can be slid on thereed-frame, moving by its slot on the staple'L.

By the movement o the block or slide J upon the reed-frame through theconnection described, between it and the reed-cover, such cover mustnecessarily be opened, that is, raised from the reed-chambers, o1closed, that is, brought down upon them, according to the direction ofthe movement of the block.

The said slide, in the closing ofthe said cover, partially twists thewire-rod E, which thus acts as a torsion-spring to hold the coverclosed, and, in the opening of' the cover, releases such twist ortorsion ot' the wire'E before commencing to lift or swing open thecover.

By my. improved arrangement and connection bctwcen a register andreed-cover described, it is manifest that. in lieu of' lifting againstthe spring provided to hold the cover closed, as in the registerconnection and arrangement employed before this invention, the pressureot' the "spring is relieved before the cover commences to rise or open,an advantage of much importance, from the fact that it facilitates theworking of the register.

In lieu of arranging the register connection with the stop, to open andclose the stop through the holdingspring, it might be arranged otherwiseto open and close the same, that is, the releasing of the spring and theoperating of the stock to be done through distinct and separate means,but operating the one after. the other, asdescrihed.

The arrangement and connection described arc deemed best, as itis mostsimple, and combines in itself both operations or movements.

Having thus described my invention,

What I claim, and desire to secure by Letters Patents, is

1. A cover or stop, C, to reeds, in combination with a spring, E,and'slide J, to which the register is vconnected, whenrelativelyarranged for relieving the pressure ot' the spring on thestop, substantially asand for the purpose described.

2. A cover or stop, O, to reeds, in combination wit-h a spring, E, whenthe spring connects the stop and register together, a-nd constitutes themeans of moving the stop through the register, substantially asdescribed.

'lhe above specification of my improvement in organstops signed by methis 16th day of April, A. D. 187 0'.
